Note 1: All parameters are production tested at T
A
= +85°C and guaranteed by design over the specified temperature range.
Note 2: Signals on COM_, NO_, or NC_ exceeding V
CC
are clamped by internal diodes. Limit forward-diode current to maximum current
rating.
Note 3: Guaranteed by design; not production tested.
Note 4:

.
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified
analog signal ranges.
Note 6: Off-isolation = 20log
